Chick Corea and his old mates were in Atlanta on a reunion concert just a couple of weeks ago. I think they were on a world tour.
With post-processing is like with salt, got to be very careful, slight overdo and the dish is spoiled.

Chick Corea is a great musician and so diverse, Nice to know your Dad has taste

In regards to your last 3 photographs, the content has been excellent.You have a great eye. But the compositions and faming have not. Why don't you see if you can find a book on composition and framing? I struggle with it too and found a few books that helped. Also, PP is a bit heavy. It distracts from the character of the image.

This is a very powerful piece Ada... you have truly captured the fulness of the moment and the treatment of the image is fantastic. I love the tactility of the composition, the texture of the brick wall, the lines on his face and hands tell their own tale and of course the faded denim ensemble that has withstood the test of time in contrast to the Cold metallic sheen of the sax and the warmth of his skin as the fuse together to produce the scathalogical vibrations we have all come to love and identify as JAzz.
Great shot.
